Description

TECHNICAL FIELD

[0001] The utility model relates to a connector assembly and a connector device comprising the same for establishing fluid communication between fluid lines. BACKGROUND

[0002] The connector device can be used in many different applications for connecting and establishing fluid communication between fluid lines. The connector device generally comprises a female connector and a male connector each connected with a fluid line, and the male connector can be inserted into the female connector to establish fluid communication between the fluid lines.

[0003] For example, some electric vehicle manufacturers currently choose the battery pack quick change technology route. Specifically, one of the female connector and the male connector is connected with a thermal management system in the battery pack, and the other is connected with a cooling liquid supply system in the vehicle, and fluid communication between the thermal management system of the battery pack and the cooling liquid supply system at the vehicle end is established by inserting the male connector into the female connector, and in order to implement the overall quick change of the battery pack, the male connector and the female connector need to be quickly connected and disconnected repeatedly, and therefore it is desirable that the connector device can quickly absorb assembly deviations in all directions when the battery pack is quickly changed.

[0004] Figures 1 to 3 An existing connector device is shown, comprising a floating connector assembly 100 (illustrated as a female connector assembly) and a mating connector assembly 200 (illustrated as a male connector assembly).

[0005] The floating connector assembly 100 comprises a base 101, a floating connector 102 (i.e. a female connector) and first and second floating units 103 and 104 for absorbing assembly deviations in all directions. The base 101 defines a base plane (XY plane) and comprises a receiving space 105 for receiving the first floating unit 103. The first floating unit 103 comprises a through hole 106 for receiving the floating connector 102 and is configured to allow the floating connector 102 to move in a radial direction of the through hole 106 and to tilt with respect to an axial direction of the through hole 106. The second floating unit 104 is mounted to four corner positions of the top surface of the base 101 and is configured to be movable with respect to the base 101 in a Z direction perpendicular to the base plane, and the floating connector assembly 100 is mounted to the vehicle body through the second floating units 104. The floating connector 102 is fluidly connected with a fluid line in the cooling liquid supply system of the vehicle and comprises a floating connector body 107 and a valve assembly 108 arranged in the floating connector body 107.

[0006] The mating connector assembly 200 comprises a mounting base 201 and a mating connector 202 (i.e. a male connector). The mounting base 201 is mounted to a case of the battery pack. The mating connector 202 is fluidly connected with a fluid line in the thermal management system of the battery pack, and comprises a mating connector body 203 and a valve unit 204 arranged in the mating connector body 203. The floating connector 102 and the mating connector 202 can be docked / plugged together, so that the valve assembly 108 and the valve unit 204 are both switched to the open state, thereby realizing fluid communication between the cooling liquid supply system of the vehicle and the thermal management system in the battery pack.

[0007] As shown in Figure 1 and Figure 3 , in the floating connector assembly 100, the floating connector body 107 comprises a first pipe segment 109 and a second pipe segment 110 which are separately formed and assembled together by clamping, which allows the second pipe segment 110 to have various configurations to adapt to different lines or tools connected to the vehicle body. In addition, the floating connector body 107 is retained on the base 101 by means of a mounting plate 111 having an opening 112 for the floating connector body 107 to pass through. The mounting plate 111 is fixed to the base 101 so that the flange 113 of the first pipe segment 109 is limited between the base 101 and the mounting plate 111 in the Z direction, thereby preventing the floating connector body 107 from being detached from the base 101.

[0008] For such a connector device, since the non-fixed external line connected with the second pipe segment 110 of the floating connector body 107 can move when the vehicle travels or performs battery pack quick change, etc., the movement of the external line can drive the floating connector body 107 to rotate relative to the base 101 about the central axis of the first pipe segment 109, which is very disadvantageous and can easily cause damage to the internal structure of the floating connector assembly 100, for example, the mounting plate 111 is broken due to the large stress, thereby reducing the service life of the connector device.

[0009] In the floating connector assembly 100 shown in Figures 1 to 3 , since the first pipe segment 109 and the second pipe segment 110 of the floating connector body 107 are assembled to form the shown approximately 90° elbow pipe, the rotation of the floating connector body 107 about the central axis of the first pipe segment 109 can be blocked by the second floating unit 104 mounted at the corner position of the top surface of the base 101. However, in some other examples, in order to match the configuration of the vehicle body, the first pipe segment 109 and the second pipe segment 110 of the floating connector body 107 can also be assembled to form a straight pipe. In this case, the rotation of the floating connector body 107 cannot be blocked by the second floating unit 104, and thus damage to the internal structure of the connector assembly can occur.

It should be understood that the drawings are intended to explain and illustrate the present application, and if necessary, help to limit the present application. DETAILED DESCRIPTION

[0038] The implementation and use of specific embodiments will now be discussed in detail. It should be understood, however, that the specific embodiments discussed are merely illustrative of specific ways to implement and use the present application and are not intended to limit the scope of the present application.

[0039] In this specification, when describing the positional relationship of the structure of each component, the expressions of orientation such as upper, lower, top, bottom, etc. are not absolute, but relative. When each component is arranged as shown in the figure, these expressions of orientation are appropriate, but when the position of each component in the figure is changed, these expressions of orientation also change accordingly.

[0040] In this specification, unless otherwise explicitly specified and limited, the terms "mounting", "connection" and the like should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrated; it can be directly connected, or indirectly connected through an intermediate medium, or the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in this specification can be understood according to the specific circumstances.

[0041] Figure 4 And Figure 5 A connector assembly 300 according to the present application is shown. It can be understood that the structure and function of the connector assembly 300 shown are similar to those of the floating connector assembly 100 shown in Figure 1 And Figure 3 That is, the connector assembly 300 is, for example, a floating connector assembly in a connector device for fluid connection with a fluid pipe in a cooling liquid supply system of a vehicle, and the entire connector device further comprises a mating connector assembly as shown in Figure 2 for fluid connection with a fluid pipe in a thermal management system of a battery pack, wherein one of the connector assembly 300 and the corresponding mating connector assembly is a female connector assembly, and the other is a male connector assembly, so that the female connector assembly and the male connector assembly can be docked / inserted with each other, thereby realizing fluid communication between the cooling liquid supply system of the vehicle and the thermal management system in the battery pack. It can also be understood that the application scenarios of the connector device 300 and the connector device comprising the same are not limited thereto, but can be used in various scenarios where fluid communication needs to be established.

[0042] As Figure 4 And Figure 5As shown, the connector assembly 300 includes a base 301, a first connector body 310, and a second connector body 320, wherein one of the first connector body 310 and the second connector body 320 forms an inlet pipe for guiding the coolant from a coolant supply system of the vehicle to the thermal management system in the battery pack, and the other of the first connector body 310 and the second connector body 320 forms an outlet pipe for guiding the coolant from the thermal management system in the battery pack to the coolant supply system of the vehicle.

[0043] The base 301 is generally plate-shaped, and a base plane defined by the base 301 is an XY plane of the base 301, i.e. a plane in which a length direction X and a width direction Y of the base 301 lie, with reference to an XYZ rectangular coordinate system in the drawing. When the connector assembly 300 is mounted to the vehicle body, the base plane is generally parallel to a mounting surface of the connector assembly 300 on the vehicle body. The first connector body 310 and the second connector body 320 are mounted to the base 301 perpendicularly to the base plane (i.e. along the Z direction), wherein the first connector body 310 includes a first protruding portion 313 protruding from (i.e. exposed to) a top surface of the base 301 and connected to the first external pipe, and the second connector body 320 includes a second protruding portion 323 protruding from (i.e. exposed to) the top surface of the base 301 and connected to the second external pipe. It can be understood that the “external pipe” referred to herein does not belong to the connector assembly 300, but is an environmental member of the connector assembly 300, for example for communicating the connector assembly 300 with the coolant supply system of the vehicle.

[0044] More specifically, in the illustrated embodiment, the first connector body 310 includes a first pipe section 311 mounted to the base 301, and a second pipe section 312 fixedly connected to the first pipe section 311 and connected to the first external pipe, the first pipe section 311 and the second pipe section 312 of the first connector body 310 are separately formed and assembled to form a straight pipe by a plurality of first clamping portions 314 and cannot move relative to each other in any direction. An upper portion of the first pipe section 311 of the first connector body 310 protrudes from the top surface of the base 301, and forms the first protruding portion 313 together with the second pipe section 312.

[0045] Similarly, in the illustrated embodiment, the second connector body 320 comprises a first pipe segment 321 mounted to the base 301 and a second pipe segment 322 fixedly connected to the first pipe segment 321 and connected to a second external pipe, the first pipe segment 321 and the second pipe segment 322 of the second connector body 320 being separately formed and assembled to each other to form a straight pipe by means of a plurality of second clamping portions 324 and cannot move relatively in any direction. The upper portion of the first pipe segment 321 of the second connector body 320 protrudes from the top surface of the base 301 and forms a second protruding portion 323 together with the second pipe segment 322. It can be understood that the shapes of the first connector body 310 and the second connector body 320 are not limited and can be determined according to the specific arrangement environment. For example, according to an unillustrated embodiment variant, one of the first connector body 310 and the second connector body 320 can form a straight pipe and the other can form a bent pipe.

[0046] Similarly to the configuration of the floating connector assembly 100 shown in Figure 1 and Figure 3 , the first connector body 310 and the second connector body 320 can be held on the base 301 by means of a mounting plate, and the mounting plate has an opening for the first connector body 310 and the second connector body 320 to pass through. The mounting plate itself is fixed to the base 301 so that the flange of the first pipe segment 311 of the first connector body 310 and the flange of the first pipe segment 321 of the second connector body 320 can be limited in the Z direction between the base 301 and the mounting plate, thereby preventing the first connector body 310 and the second connector body 320 from being detached from the base 301.

[0047] It can be understood that the "first pipe segment" of the first / second connector body in the illustrated embodiment constitutes a valve housing of the connector body, which is fixedly mounted to the base 301 and fixedly connected to the second pipe segment in the above-mentioned manner; in addition, the internal fluid passage of the valve housing is provided with a valve assembly (for example, the valve assembly 108 in Figure 3 ), and the internal fluid passage of the valve housing can receive a valve unit (for example, the valve unit 204 in Figure 3 ) of another mating connector assembly to achieve fluid communication through the mating cooperation of the valve assembly and the valve unit. The "second pipe segment" of the first / second connector body is arranged outside the base 301 as part of the connector assembly 300, for connecting the internal fluid passage of the valve housing with an external pipe.

[0048] According to the utility model, first connector body 310 includes setting on first protruding portion 313 first blocking portion 330, second connector body 320 includes setting on second protruding portion 323 second blocking portion 340, wherein, this first blocking portion 330 for example is integrally formed on the outer wall of the upper portion of the first pipe section 311 of the first connector body 310 protruding from the top surface of the base 301, and / or, the second blocking portion 340 for example is integrally formed on the outer wall of the upper portion of the first pipe section 321 of the second connector body 320 protruding from the top surface of the base 301, first blocking portion 330 and second blocking portion 340 are configured to be clamped with each other, to prevent each of first connector body 310 and second connector body 320 from rotating in any direction around the respective Z-direction central axis perpendicular to the base plane due to the influence of the corresponding external pipeline movement, so that the internal structure (such as mounting plate and other components) of the connector assembly 300 can be protected from the damage caused by such rotation.

[0049] According to another unshown implementation variant, for example in the case where the upper portion of the first pipe section 311 of the first connector body 310 protruding from the top surface of the base 301 is at least partially covered by the second pipe section 312 of the first connector body 310, the first blocking portion 330 can be formed on the outer wall of the second pipe section 312 of the first connector body 310; and / or, in the case where the upper portion of the first pipe section 321 of the second connector body 320 protruding from the top surface of the base 301 is at least partially covered by the second pipe section 322 of the second connector body 320, the second blocking portion 340 can be formed on the outer wall of the second pipe section 322 of the second connector body 320 to be clamped with the first blocking portion 330.

[0050] As shown in Figs. Figures 6A to 6D and Figures 7A to 7D According to a preferred implementation, the first blocking portion 330 is a substantially U-shaped first hook portion extending from the outer wall of the first protruding portion 313 of the first connector body 310, which substantially U-shaped first hook portion comprises a first inner wall 333, a second inner wall 334 and a third inner wall 335 successively extending from the first connector body 310 and jointly delimiting a first recess 331. It can be understood that the first inner wall 333 and the third inner wall 335 constitute two opposite side walls of the first recess 331, and the second inner wall 334 constitutes a bottom wall of the first recess 331, and the substantially U-shaped first hook portion has a first free end portion 332 formed at the end thereof, which first free end portion 332 is jointly delimited by the third inner wall 335, an outer wall 337 opposite to the third inner wall 335, and an end wall 336 connecting the third inner wall 335 and the outer wall 337. It can be understood that the "free end portion" of the hook portion referred to herein is the other end of the hook portion opposite to the end portion connected to the protruding portion of the connector body.

[0051] Similarly, according to this preferred embodiment, the second blocking portion 340 is a generally U-shaped second hook portion extending from the outer wall of the second protruding portion 323 of the second connector body 320. The generally U-shaped second hook portion has substantially the same shape and size as the first hook portion and includes a first inner wall 343, a second inner wall 344, and a third inner wall 345 extending sequentially from the second connector body 320 and collectively defining a second recess 341. It will be appreciated that the first inner wall 343 and the third inner wall 345 constitute two opposing side walls of the second recess 341, the second inner wall 344 constitutes the bottom wall of the second recess 341, and the distal end of the generally U-shaped second hook portion forms a second free end portion 342, which is collectively defined by the third inner wall 345, an outer wall 347 opposite to the third inner wall 345, and an end wall 346 connecting the third inner wall 345 and the outer wall 347. The first free end portion 332 of the first blocking portion 330 is positioned in the second recess 341 of the second blocking portion 340 and snap-fitted with the second recess 341 , and the second free end portion 342 of the second blocking portion 340 is positioned in the first recess 331 of the first blocking portion 330 and snap-fitted with the first recess 331 .

[0052] The following briefly describes the anti-rotation working principle of the first blocking portion 330 and the second blocking portion 340. In the following description, "clockwise" rotation refers to clockwise rotation of the first connector body 310 and the second connector body 320 about their respective Z-axis centers relative to the base 301 in the top view, while "counterclockwise" rotation refers to counterclockwise rotation of the first connector body 310 and the second connector body 320 about their respective Z-axis centers relative to the base 301 in the top view.

[0053] like Figure 6A and Figure 7AAs shown, when the first connector body 310 and the second connector body 320 simultaneously exist the tendency of clockwise rotation, the first free end 332 of the first blocking portion 330 and the second free end 342 of the second blocking portion 340 closely abut each other, more specifically, the third inner wall 335 of the first blocking portion 330 and the third inner wall 345 of the second blocking portion 340 closely abut each other, so that the third inner wall 335 of the first blocking portion 330 and the third inner wall 345 of the second blocking portion 340 are respectively subjected to the opposite first supporting force F1 and the second supporting force F2, thereby being able to block the first connector body 310 and the second connector body 320 from simultaneously rotating clockwise around the respective Z-direction central axes. Preferably, the third inner wall 335 of the first blocking portion 330 forms an acute included angle with the second inner wall 334, and the third inner wall 345 of the second blocking portion 340 forms a corresponding acute included angle with the second inner wall 344, and such a configuration ensures a more firm abutment between the third inner wall 335 of the first blocking portion 330 and the third inner wall 345 of the second blocking portion 340.

[0054] As shown, when the first connector body 310 and the second connector body 320 simultaneously exist the tendency of clockwise rotation, the first free end 332 of the first blocking portion 330 and the second free end 342 of the second blocking portion 340 closely abut each other, more specifically, the third inner wall 335 of the first blocking portion 330 and the third inner wall 345 of the second blocking portion 340 closely abut each other, so that the third inner wall 335 of the first blocking portion 330 and the third inner wall 345 of the second blocking portion 340 are respectively subjected to the opposite first supporting force F1 and the second supporting force F2, thereby being able to block the first connector body 310 and the second connector body 320 from simultaneously rotating clockwise around the respective Z-direction central axes. Preferably, the third inner wall 335 of the first blocking portion 330 forms an acute included angle with the second inner wall 334, and the third inner wall 345 of the second blocking portion 340 forms a corresponding acute included angle with the second inner wall 344, and such a configuration ensures a more firm abutment between the third inner wall 335 of the first blocking portion 330 and the third inner wall 345 of the second blocking portion 340. Figure 6B Figure 7B As shown, when the first connector body 310 and the second connector body 320 simultaneously exist the tendency of clockwise rotation, the first free end 332 of the first blocking portion 330 and the second free end 342 of the second blocking portion 340 closely abut each other, more specifically, the third inner wall 335 of the first blocking portion 330 and the third inner wall 345 of the second blocking portion 340 closely abut each other, so that the third inner wall 335 of the first blocking portion 330 and the third inner wall 345 of the second blocking portion 340 are respectively subjected to the opposite first supporting force F1 and the second supporting force F2, thereby being able to block the first connector body 310 and the second connector body 320 from simultaneously rotating clockwise around the respective Z-direction central axes. Preferably, the third inner wall 335 of the first blocking portion 330 forms an acute included angle with the second inner wall 334, and the third inner wall 345 of the second blocking portion 340 forms a corresponding acute included angle with the second inner wall 344, and such a configuration ensures a more firm abutment between the third inner wall 335 of the first blocking portion 330 and the third inner wall 345 of the second blocking portion 340.

[0055] As shown, when the first connector body 310 and the second connector body 320 simultaneously exist the tendency of clockwise rotation, the first free end 332 of the first blocking portion 330 and the second free end 342 of the second blocking portion 340 closely abut each other, more specifically, the third inner wall 335 of the first blocking portion 330 and the third inner wall 345 of the second blocking portion 340 closely abut each other, so that the third inner wall 335 of the first blocking portion 330 and the third inner wall 345 of the second blocking portion 340 are respectively subjected to the opposite first supporting force F1 and the second supporting force F2, thereby being able to block the first connector body 310 and the second connector body 320 from simultaneously rotating clockwise around the respective Z-direction central axes. Preferably, the third inner wall 335 of the first blocking portion 330 forms an acute included angle with the second inner wall 334, and the third inner wall 345 of the second blocking portion 340 forms a corresponding acute included angle with the second inner wall 344, and such a configuration ensures a more firm abutment between the third inner wall 335 of the first blocking portion 330 and the third inner wall 345 of the second blocking portion 340. Figure 6C Figure 7C As shown, when the first connector body 310 and the second connector body 320 simultaneously exist the tendency of clockwise rotation, the first free end 332 of the first blocking portion 330 and the second free end 342 of the second blocking portion 340 closely abut each other, more specifically, the third inner wall 335 of the first blocking portion 330 and the third inner wall 345 of the second blocking portion 340 closely abut each other, so that the third inner wall 335 of the first blocking portion 330 and the third inner wall 345 of the second blocking portion 340 are respectively subjected to the opposite first supporting force F1 and the second supporting force F2, thereby being able to block the first connector body 310 and the second connector body 320 from simultaneously rotating clockwise around the respective Z-direction central axes. Preferably, the third inner wall 335 of the first blocking portion 330 forms an acute included angle with the second inner wall 334, and the third inner wall 345 of the second blocking portion 340 forms a corresponding acute included angle with the second inner wall 344, and such a configuration ensures a more firm abutment between the third inner wall 335 of the first blocking portion 330 and the third inner wall 345 of the second blocking portion 340. ​​
